Dismissed for crashing a van and trying to hide it – protected disclosures did not save him
A depot technician with 12 years' service was dismissed after reversing a work van into a tree and attempting to repair the damage himself. The tribunal upheld the dismissal, finding it was for misconduct, not because of his protected disclosures.

Key facts
- The claimant was employed as a Depot Infrastructure Technician from 25 July 2011 until dismissal on 3 August 2022.
- He received a final written warning on 25 May 2022 for safety-related incidents, with zero tolerance for further errors.
- On 21 June 2022, he reversed his work van into a tree and attempted to repair the damage himself before reporting it the next day.
- He was dismissed for misconduct, specifically failing to report the accident immediately and attempting to conceal the damage.
- The claimant had made seven protected disclosures about health and safety concerns, which the respondent accepted as protected.
- The tribunal found that the protected disclosures were not the principal reason for dismissal; the reason was conduct.

The legal issue
The tribunal had to decide whether the dismissal was automatically unfair because the claimant had made protected disclosures about health and safety concerns, or whether it was a fair dismissal for misconduct.
The outcome
The tribunal dismissed all claims. It found that the claimant was dismissed for conduct – failing to report a work van accident and attempting to cover it up – and that this was a fair reason. The protected disclosures were accepted as genuine but were not the reason for dismissal.
- The employer had a genuine belief in the misconduct after a reasonable investigation.
- The decision to dismiss fell within the range of reasonable responses, especially given the claimant's recent final written warning with zero tolerance.
- No compensation was awarded.
Lessons & takeaways
- Making protected disclosures does not give you immunity from dismissal for separate misconduct – the employer must still show that the disclosures were not the reason for the decision.
- A final written warning with a zero-tolerance policy significantly increases the risk of dismissal for any further breach, even a minor one.
- If you are involved in an incident at work, report it immediately – attempting to cover it up can be treated as gross misconduct in itself.
This case shows the limits of whistleblower protection. The claimant, a Depot Infrastructure Technician with 12 years' service, had raised several health and safety concerns about asbestos and other issues. Those disclosures were accepted as protected, but they did not save his job when he later crashed a work van and tried to fix the damage himself before reporting it the next day.
What went wrong
The employer, Govia Thameslink Railway, had already given the claimant a final written warning for safety lapses just a month before the van incident. That warning came with a zero-tolerance message: any further errors would lead to dismissal. When the claimant reversed into a tree and then spent time trying to repair the dent with a hammer and filler, he breached that warning. The employer's investigation found he had failed to report the accident immediately and had attempted to conceal the damage – classic gross misconduct.
The tribunal accepted that the claimant genuinely believed he was raising safety issues, but the decision to dismiss was about conduct, not the disclosures. The employer had carried out a reasonable investigation and genuinely believed the claimant had committed the misconduct. Given the final warning and the nature of the cover-up, dismissal was within the range of reasonable responses.
What the employer did right
The employer suspended the claimant, investigated promptly, and held a disciplinary hearing. The decision-maker, Mr Poole, considered the claimant's long service and the protected disclosures but concluded that the misconduct was too serious to overlook. The appeal process also considered the claimant's arguments but upheld the dismissal, though it changed it from summary to notice pay.
Why this matters
For employees, this is a reminder that whistleblowing protections are not a blanket shield. If you commit separate misconduct – especially after a final warning – you can still be fairly dismissed. For employers, the case confirms that a reasonable belief in misconduct, backed by a proper investigation, will usually defeat an unfair dismissal claim, even when the employee has made protected disclosures.
